10 cal/ whom, it may concern:

Be it known that I, CHARLES J. TAGLIABUEE citizen of the United States,and a resident of Brooklyn, county of Kings, city and State of New York,have invented certain new and useful Improvements in Thermometers, ofwhich the following is a specification.

My invention relates to clinical thermometers, and has for its object toprovide a simple and efcient means for securing said thermometers in aprotecting-case.

Other objects of my device will appear from the detailed descriptionfollowing hereinafter, and the features of novelty will be pointed outin the appended claims.

Reference is to be had to the accompanying drawings, in which-- Figure lis an elevation, partly in section, of a thermometer with my inventionapplied thereto. Fig. 2 is a view illustrating another position of thethermometer, and Fig. 8 is a detail section of the means for securingthe end of the thermometer in the fastening device.

A represents athermometer of any approved construction, which isprovided with a bead A at the end opposite to the bulb A2.

B is a thimble which is slipped over the thermometer and is providedwith a polygonal flange B3, and O is a washer of rubber or any othersuitable material which is placed between the head A of the thermometerand the thimble B. The said thimble B is provided with adownwardlyprojecting portion B', which is screw-threaded to receive anut or cap D, this nut or cap D serving to firmly secure the end of thethermometer in the thimble B. A ring or eye D is secured to the cap Dfor purposes which will be more fully described hereinafter. The thimbleB is further provided with an upwardly-projecting portion B2, which isalso screw-threaded and which is arranged to be screwed into theprotecting-case E when the thermometer is not in use, said case beingprovided with a mating screw-thread at its open end for this purpose.The protecting-case E is provided at its closed end with a ring or eyeE, to which is attached. one end of a chain F.- To the other or free endof the chain is secured a fastening device G, Such as a safety-pin,which may be fastened to the garment of the user of the thermometer toprevent the case and thermometer from being mislaid.

Another and important use of the chain and fastening device will now bedescribed. After the physician or other person has used the thermometerto take a temperature and it is desired to return the mercury to thebulb the safety-pin or other device G is first unfastened from thegarment of the user and then connected with the ring D of the cap D, asclearly shown in Fig. 2. The case E is then firmly grasped in the handof the physician or other person and the thermometer rapidly whirledaround in a circle a few times, whereupon it will be found that themercury has been completely returned to the bulb by centrifugal force.This device thus does away with the danger of breaking the thermometerby the common way of returning the mercury to the bulb-as, for instance,by striking the hand holding the thermometer upon the knee or otherobject or rapidly moving the thermometer in the air with a sort ofstriking or jerky movement. My invention also overcomes thedisadvantages resulting from fastening' one end of the thermometer in acap or thimble with sealing-wax, as is the usual custom.

Writh a fastening device constructed according to my invention there isno danger of the thermometer becoming' loose in the cap by thesoftening' of the sealing-wax or other fastening medium, the nut or capD serving to firmly secure the parts together.

My device also has the material advantage of being very easily takenapart and put together again, it being only necessary to unscrew the capD and slip the thimble B over the thermometer, the reverse operationtaking place when it is desired to reassemble the parts.

Various modifications may be made without departing from the nature ofmy invention.

I claim and desire to secure by Letters Patent- 1. The combination witha thermometer, of a tubular securing device through which saidthermometer is arranged to project, said securing device being providedwith a flange, a cap adapted for engagement with the securing device onone side of the flange against which said cap abuts, for securing saiddevice and the thermometer together, anda protecting-case into which thethermometer is adapted to be inserted when not in use, said case beingarranged to engage the securing device, on the other side of said flangeagainst which said case abuts when in position.

2. rFhe combination with a thermometer having a bead at one end, of athimble adapt- IIO ed to be slipped on the thermometer andhaving itsbore enlarged at one end to receive said bead, both ends of the thimblebeing screw-threaded, a Washer contained between the head and thethimble, a cap Screwed on one end 'of the thimble and engaging thebeaded end of the thermometer` and a oase screwed on the other end ofthe thimble.

8. The combination of a, thermometer', a case therefor, a flexiblemember Connected With said ease at the end opposite to that at which thethermometer enters said case and an attaching device for securing Saidflexible melrnber to the thermometer opposite to the bu b.

In testimony Whereofl have signed my name to this specificationin thepresence of two subscribing Witnesses.
